Alright... I was trying not to join in on this but can we all admit there's no "right" answer here?...
Why? Because different people react differently to diff touches, right? I can only speak for me. I bruise easily and am off the charts sensitive. If you do the pincher lobster claw thing (which I hear works for some girls, that's great.) For me, it'll get you knee'd in the face if I'm able.
Try to play Leo, get creative~for me, soft, slow circles DEMOLISH me anywhere on my body. Especially around my belly button. Start with big circles and slowly get smaller. or vice versa. Use soft sensual things like a feather or q-tip in her belly button. Make it fun, feel like teasing, tie her up, place a pillow under her back....
